ESA enrolls in SSTL’s Lunar Pathfinder

Must Read

“SSTL’s Lunar Pathfinder service will be available to all, enabling lower cost lunar science, technology demonstration and commercial exploration. As a leader in lunar exploration, ESA plans to use its services extensively.” Exploring the far side of the Moon, particularly the South Pole Aitkin Basin, is a key area for future robotic and human exploration due to its chemical and mineral composition. The stable elliptical orbit of Lunar Pathfinder will enable long duration visibility of the Southern Lunar Hemisphere each day, maximising opportunities for data relay between Earth and the lunar surface.

The spacecraft will operate two simultaneous channels of communication with lunar assets, one in S-band and one in UHF, while communications back to Earth ground stations will be sent in X-band. In addition to its core communications role, Lunar Pathfinder will also host a number of science and navigation experiments including an ESA GNSS receiver capable of detecting weak signals coming from Galileo and GPS satellites orbiting Earth, a NASA retro-reflector to demonstrate laser ranging capabilities and an ESA radiation monitor to study orbital radiation conditions.

“We have been collaborating with ESA since 2018 to scope our Lunar Pathfinder mission for the commercial market, and we look forward to realising our ambition to provide cost effective services and navigation data for lunar assets.” “We are delighted to sign up ESA as our anchor customer for communication services from our Lunar Pathfinder mission,” said Phil Brownnett, managing director of SSTL.
